WTL的CBitmapButton在MFC下完美使用

MFC下的CBitmapButton我觉得是牛脾气的难用，WTL的这个不错，完全自绘，使用也简单方便

现在改装好并结合MFC的方式，下附源码及使用例子:

代码移植于WTL的CBitmapButton,可以在MFC下完美的使用

使用方法：

CImageList imageList; imageList.Attach(ImageList_LoadImage(AfxGetResourceHandle(),MAKEINTRESOURCE(IDB_LOGONBTN), 76, 4,CLR_NONE, IMAGE_BITMAP, LR_CREATEDIBSECTION)); m_logonbtn.SetImageList(imageList); m_logonbtn.SetImages(0, 1, 2, 3); m_logonbtn.SetBitmapButtonExtendedStyle(BMPBTN_HOVER, BMPBTN_HOVER); m_logonbtn.SetToolTipText(_T("登陆")); imageList.Detach();

 

效果：
